Improvement in broadcast-sowers



PA'IENT DAVID BUIST AND CHARLES E. ALDEN, OF PHILADELPH 1A, PENNSYLVANIA.

IMPROVEMENT IN BROADCAST-SOWERS.

Specific aton forming part of Letters Patent N0.186,410 dated J annary 23, 1877 application filed June 21, 1876.

T all whom it may concern Be it known that we, DAVID BUIST end HAS. E. ALDEN, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and usefui Improvements in Broadcast-Sowers; and we do hereby declare the following to be a full, clear, and exact descripticn of theinvention, such as Will enable others skilled in the arts te which it pertains to make.and use it, reference being had to the accompanying of which the grain,cr other substance to be sown, may be thrown a greater distance than was heretofore obtainable by machines of this elass; end, secondly, to provide for the hopper a nozzle 0r delivery end of peculiar construction, by means of which the grain, or other matter to be sown, will be delivered t0 thescatterer in such manner that it will be thrown oniy from the front; half of said sca'c-- terer, thus dispensing with the rear guard or shield heretofore required, said nozzle being als0 adjustable, so that when, for any reason, it may be desired t0 s0w on only one side of the track of the machine, such result may be accomplished.

Our improvements acc0rdingly consisi: in the pecular construction of Ghe distributingwheel and hopper-nozzle, and in the combination of said parbs, as hereinafter more 'ully described.

Referring to the acccmpanying drawing, A designates the distributing-yvheel, composed of a flat; metallicdisk, having curved radial ribs or partitions B B, which incline from the sur face of the disk backwardly, s0 as to form an obtuse angle on their front side. The disk A is siotted or cut just back of each of the ribs B, as shown at a, and the metal of the disk struck up to form an inciine or lift, C, the edge of which meets the back of the rib at b.

liiting motion just before ii leaves the disk,

whereby it is carried mach farther than it would be i said wheel.were n0'c formed with the lift, as described.

D representzs the hopper formed with a removabie or rotery neck, E, which serves as a. nozzle 0r delivery end. Said nozzle is preferabiy of the form of a short cylinder, e, with beveled 0r inclined bottom efi, the lowest edge of which is cut: away, s0 as to leave a curved opening, e between it and the wall of said cyiinder. '1he shaft; F, by which the wheel is rotated, passes through a centrallyiocated elongated slot,f, in the bottom 0 The nozzle E being arranged on the hopper D so that bhe Opening 6 Will be fcrward of a line drawn transversely through the center of the disk A, the grain or other material ied from the hopper Wll 'all in front of said line, and will be thoroughly scattered without any porbion of it falling back of said line.

By this means the shield or guard heretofore required in machines in which the mate r1alto be 'ed was delivered in the center of the Wheel, and was therefor scattered equally in every direction, is dispensed With. A saving is, therefore, efi'ected in the first; cost of the machine, aud the labor heretofore entailed by the necessity of picking up the grain thrown againsl; the shield, and putting the same back in the hopper, is avoided.

By turning the nzzle E around s0 as to cause the slot e 130 cross a line drawn transversely through the center of the disk, the machine may be made '00 sow oneiher the right 0r left side alone, or more to ne side than another, the feed being duly graduated by means of the cutofi' slide G.

The mprovements herein described may be applied t:o hand as well as wheeled sowers, and the parts described may be made of metal or any other material.

The invention may be applied t0 sowing seed, and to distaributing ferilizers, lim e, &c.

What we claim as 0111 invention is-- 1. The distributing-wheel composed of the disk A, having the lift 0 and slopng curved ribs B, substantially as shown and descrbed.

2. The delivery-nozzle composed of the oylinder e, having inolned bottom 6 and. slot 6, substantially as shown and described.

3. In combination With a distribut-ng-wheel 01 scatterer of a sowing-machine, a rotary hopper-nozzle, adjustable, s0 as '00 hring its feed-opening across a line drawn IJrans versely through the middle of sad Wheel, and thus cause the latter t0 scatater wholly on one sde of the track of the machine, or more on one sde tha n on the other, substantially as shown and glescribed.

In testimony that we claim the foregoing we have hereunto set: 0u1 hands this 16th day of June, 1876.
